ABSTRACT:
A stacking and surface protection device is disclosed on a protective housing made of a synthetic material. The stacking and surface protection device has at least two raised supports in the form of supporting feet (14, 15) molded on each of the outer surfaces (10, 11, 12, 13). These supporting feet (14, 15) have contact surfaces made so that two supporting feet (14, 15) on an outer surface are male and female elements with respect to their contact surfaces and interlock when the outer surface is rotated by 180.degree. around a vertical as well as a horizontal axis. As a result, protective housings stacked on top of each other, i.e. outer surfaces lying on top of each other are blocked in two degrees of freedom of the stacking plane. A stacking and surface protection device having stacking support surfaces of identical configuration by means of which stable stacks can be obtained while the smooth synthetic material surfaces are effectively protected against scratching and soiling is thereby created.
